Analog Devices Inc./Maxim Integrated

The MAX14585/MAX14585A high-ESD-protected double-pole/double-throw (DPDT) switches multiplex Hi-Speed (480Mbps) USB and analog signals such as AC-coupled audio or video. These devices combine the low on-capacitance (CON) and low on-resistance (RON) necessary for high-performance switching applications in portable electronics and include an internal negative supply to pass audio signals that swing below ground down to -1.8V. The devices also handle USB low-/full-speed signaling and operate from a 2.7V to 5.5V supply.The devices feature a VBUSdetection input (VB) that can handle voltage up to 28V to automatically switch to the USB signal path upon detection of a valid VBUSsignal (VB> VVBDET). In a dead battery situation, the voltage on VBcan supply power to the part if VBis greater than 4.5V. The MAX14585 features internal shunt resistors on the audio path to reduce clicks and pops heard at the output.The MAX14585/MAX14585A are available in a space-saving, 10-pin, 1.4mm x 1.8mm UTQFN package and operate over the -40°C to +85°C temperature range.ApplicationsCell PhonesPDAs and Handheld DevicesTablet PCs

The MAX14589E/MAX14594E high-density, double-pole/double-throw (DPDT) analog switches feature Beyond-the-Rails™signal capability that allows signals from -5.5V to +5.5V to pass without distortion even when the power supply is below the signal range. The low RONresistance (0.2Ω) makes the devices ideal for low-distortion switching, such as audio.The MAX14594E has internal shunt switches that discharge the audio amplifier AC-coupling capacitance at the normally open (NO1 and NO2) terminals. This feature reduces click-and-pop sounds that occur when switching audio signals between precharged points.The switches are fully specified to operate from a single +1.6V to +5.5V power supply. Because of the low supply current requirement, VCCENcan be provided by a GPIO. When the power is not applied, switches go to a high-impedance mode and all analog signal ports can withstand signals within the analog signal range. The devices control the switches with a control bit, CB.The MAX14589E/MAX14594E are available in a 1.2mm × 1.2mm, 0.4mm pitch, 9-bump wafer-level package (WLP) and operate over the -40°C to +85°C extended temperature range.ApplicationsPortable Audio/Video EquipmentPortable Navigation DevicesSmartphonesTablets

The MAX14591 is a dual-channel, bidirectional logic-level translator with the level shifting necessary to allow data transfer in a multivoltage system. Externally applied voltages, VCCand VL, set the logic levels on either side of the device. A logic signal present on the VLside of the device appears as the same logic signal on the VCCside of the device, and vice-versa.The device is optimized for the I²C bus as well as the management data input/output (MDIO) bus where often high-speed, open-drain operation is required. When TS-bar is high, the device allows the pullup to be connected to the I/O port that has the power. This allows continuous I²C operation on the powered side without any disruption while the level translation function is off.The part is specified over the extended -40°C to +85°C temperature range, and is available in 8-bump WLP and 8-pin TDFN packages.ApplicationsDevices with I²C CommunicationDevices with MDIO CommunicationGeneral Logic-Level Translation
